Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg whites
Coagulate and collect impurities as they heat, helping the jelly come out clear.
Sugar
Sweetens and thickens the liquid so it sets into a jelly.
Lemon juice
Adds acidity that brightens flavour and helps the jelly set.
Strong ale or porter
Provides the main liquid and the malty, bitter flavour of the jelly.

The step that matters

Let it drain until clear. Pouring the mixture into the jelly bag and letting it drain slowly, without squeezing, keeps the coagulated egg white and sediment behind so the jelly stays clear.
